Math quizzes

Hey all,
I decided to create a math quizzes that everyone on the forum can answer.

1) Let ABCD be a parallelogram where E is a point between AB such that 3BE = 2DC The lines CE and BD intersect at the point Q. If the area of <DQC is 36. Find the area of <BQE.

More to come...

Re: Math quizzes

Hi;


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.

Re: Math quizzes

Yes, both of you are correct.

2) Let n and k be two positive integers such that k is less than n. It is know that (1+2+3+4+...+n)+k = 101. fFind k.

Re: Math quizzes

Yes. Hmm...
3) Let 0 < y < 1. If A = y, B = y^2, C = 1/y and D = 1/y^2 arrange them from the largest to the smallest value.

How to do the message thing btw?

Hi;

Use the hide tags.

and put what you want to hide between them. Yes I changed the order.

Re: Math quizzes

4) Using only the numbers 1, 2, 3, 6, 7, 9, 0. Find which number goes with each of the letter in the addition problem below to make it correct. PAK = MAK = PIUT (I got this question for someone, I don't have a answer.)

5) Solve 200520062007^2 - 200520062006 x 200520062008 = (You are not allowed to use a calculator!)

That's all for now.
